FREEZER CONTROLLER Model FA3F

ATTENTION Firmware V8

Read carefully these instructions before installing and using this device and keep them for future reference. Attention to installation and electrical wiring. Use this device

only as described in this document and never use itself as a security device. The device must be disposed of in accordance with local standards for the collection of

electrical and electronic equipment.

DESCRIPTION

FΑ3F is a temperature controller for freezer cabinets with defrost control; room and evaporator temperatures are controlled with NTC/PTC sensors; 3 indication digits with

resolution 0.5°C and 4 buttons; one digital input for controlling the cabinet’s door; 3 relays: compressor 30Α 250VAC, fan 10Α250VAC, defrost 10Α250VAC; defrosting may

be electric or hot gas, a buzzer in case of an alarm. Smart defrost is also available for power saving and better control of the defrost procedure. The device is mounted on a

panel hole and it is restrained with plastic side brackets. Through the serial input it can be connected to a network either through Cloud IoT on the CORTEX platform or through

a local computer with the CAMIN program for complete local recording and monitoring of the device.

TECHNICAL SPECIFICATIONS

FA3F connects via serial input to the following options:

Cloud IoT CORTEX platform: connection to the cloud and the CORTEX platform for monitoring - recording and managing the thermostat from your mobile, tablet or any

computer, notifications via email and Viber SMS

CAMIN program: local connection and monitoring - recording and management of the thermostat through the CAMIN program installed on a local computer.

Mini Logger recorder: the thermostat can be connected to the recorder and record based on selected minutes on a microSD memory card, its temperatures and the state

of the relays and alarms. It is connected via a cable to the serial input and we program the parameter Add = 1.

Memory key: the parameter values are stored in the memory key or recorded by it in the thermostat.

Smart defrost operates in parallel and independently from the conventional defrost. Both defrost modes can operate at the same time based on the respective settings. By

enabling smart defrost, it is recommended to adjust conventional defrost to operate in safe mode - for example once every 48 hours: parameter No 22, dFr = 48. If smart

defrost is not executed, then the conventional defrost will start after 48 hours from the last successful defrost. Each time a smart defrost is executed, the timer of the

conventional defrost is renewed.

Smart defrost is activated from parameter No 29, dSE = 1.

It is recommended during the start-up of the temperature controller, to execute a smart defrost cycle, parameter No 30, dSb = 1.

ATTENTION: according to safety standards, the device must be properly positioned and protected from any contact with electrical parts. The device must be fastened in such a way that it cannot

be removed without the use of tools. Disconnect the main safety switch of the installation before proceeding to any maintenance. Disconnect the power supply of the device before proceeding to

any maintenance. Do not place the device near heat sources, equipment containing strong magnets, in areas affected by direct sunlight or rain. Prevent electrostatic discharges and sharp objects

from been inserted to the device. Separate signal cables from power supply cables to prevent electromagnetic disorders. Signal cables must never be in the same pipe with the power supply cables.

ATTENTION: Read carefully the technical specifications and make sure that the working conditions are appropriate. According to safety standards, the device must be fastened in such a way that

it cannot be removed without the use of tools.

Dimensions are in mm. The device is mounted on panel hole with cut 29x71mm and restrained with plastic side brackets.
